Okay, so I'm new at this coding. I was able to code no seatbelt warning and digital speedometer. but now, my fuel, oil temp, and tachometer doesn't work. I'm not sure what I did wrong. How can I reset everything back to normal? like remove all coding?

Reset the module by loading the experten mode profile.
Just like in normal coding you choose the e89 chassis and read VIN from cas. Press "back", then "Process ECU".
Choose frm/nfrm and click "Execute job".
This will code the standard values from the vehicle order.

Some options dont work for some years, maybe you edited the wrong one.

I just coded two things: SBR_FAHRER_1 in ABG module and BC_DIGITAL_V in KOMBI module. I didn't change anything else. I used the diy pdf and files on the sticky to code. I also reverted the coding, but still no work.

Yes, I'm actually looking at a few threads with similar problem. When you guys say use expertmode and recode. Do you mean loading expertmode, press f1, f3, choose cas, press back, process ecu, choose each module, and execute job?

Choose cas then choose Kombi then read the kOmbi module and then go straight to job and choose Sg_coderien and execute job

Coding is not a game. You should really do a thorough research and read into it more and gain an understanding of what is needed to code a car. You can easily Mess things up quickly. If u would have researched and read then you should already know updating the the most recent spdaten files is a must.

I just used v46, expertmode and what you told me. It didn't work. I will try again. Maybe I need to use older daten files?

Your daten files are older than what is on your car. It has been discussed many times before. A sticky thread was even created for this exact issue.

Download latest daten files and then code module to default.

In this case just KOMBI since the only module responsible for your tach is such

Make sure you properly updated respective folders.

This seems to be condensed down to 2006 production year cars with recently updated KOMBI at the dealer using old files.

backing up your trc file does nothing for you. Your settings are already determined by your vin and VO string, which means all you have to do is expertmode >> execute job. In this case, its a difference in functions your car isnt familiar with from what you flash it with, so it freaks out and stalls. TRC files only contains converted hex values into simple active, not active, pre designated values per function ei reversible
